Birds are much faster and thrown at angles you never saw before. 15 machines set at fixed angles and controlled by computer. Competitors shoot the same menu of targets, just in a different order. Also an ammo restriction, 24 gram, 7/8 oz shells are used. And there are six man squads, one shot per station, with one man in motion from station 5 to station 1 while the shooting continues. HMB

This is an addictive discipline, and you think you have it mastered by shooting 23 or 24, when it comes and bites you back and you shoot a 18 or 19.
Many shooters trying this discipline, after shooting American trap, think the targets are going really fast, (which in principal they are compared to what they are used to)but the way to shoot it is to allow the eye a few moments extra to see the clay properly and then attack it smoothly. Most mistakes are because the shooter 'thinks' they have to shoot it fast, when in reality the slower and smoother they move the faster the target is shot. It is no good throwing you gun at the clay and then waiting for it to catch you up.
Have a go...it's great fun.

That is an open ended question.
What exactly do you mean by vision?
Where to look for the clay?
How to look for it?
All sorts of options about eyes...the basic one is to make sure that your eyes are still and ready to see the clay before you call for it.
Where to put them really depends on where your gun hold is and if you shoot with one or two eyes.
What i will say though, is the eyes are in charge of everything.
